What I mean is that anyone (in fact there were projects that did this) could make an image with an installer GUI for Arch Linux that installed Arch Linux and some opinionated software like Endeavour does. But at the end you just got an easy Arch installation. What bothers me is that instead of pushing for Arch Linux’s brand, Endeavour created their own, virtually wrapping Arch Linux as theirs, and I don’t believe it is enough work to consider it a different distro, because it is LITERALLY ARCH with a couple of extra packages (that could be on the main repos or the AUR).
And I am saying all this as an Endeavour user myself!
